Scripture vs. Personal opinion

Personal opinion fuels today’s America. Everyone has an opinion, but most don’t have a basis to go on. Everyone thinks they have it all figured out and “everyone else would just be better off if they knew what you knew.” Regardless of actual science, history, or other people’s experiences, if it doesn’t sound emotionally satisfying we just don’t accept it.
Opinion all too often overrides conversations. Instead of listening, everyone forces their opinion or knowledge into conversations. Conversations are becoming a battle of last words than a humble experience.
The question becomes: What is our source of truth? Is it ourselves, others, or God? Only one stands up, all others constantly fall short and change. You know this to be true in your own life. Everyone is in desperate need of God. Instead of filling up on man’s empty opinions, why not look to scripture? What does scripture say about certain circumstances? We have to constantly realign ourselves with scripture. This is our basis for life, not how much we think we know.
If you think this is ludicrous, what is your source of truth? How often have you been wrong? What makes you think you’re the only one who has this whole thing figured out? What will it take for you to realize you’re not in control and that you don’t know it all?
